Abstract

A programmable A/D converter is designed with 8 N and P channel MOSFETs, respectively. In order to observe linear programmability of the EEPROM device during programming mode, a cell is developed with a 1.2 ${\mu}{\textrm}{m}$ double poly CMOS fabrication process in MOSIS. It is observed that the high resolution, of say 10m Volt, is valid in the range 1.25volts to 2volts. The experimental result is used for simulating the programmable 8 bit A/D converter with Hspice. The A/D converter is demonstrated to consume low power, 37㎽ by utilizing a programming operation. In addition, the converter is attained at the conversion frequency of 333 MHz.

8개의 N과 P채널 EEPROM을 이용하여 A/D 변환기를 설계하였다. 프로그래밍 모드에서 EEPROM의 선형적 저장능력을 관찰하기 위해 MOSIS의 1.2㎛ double-poly CMOS 공정을 이용하여 셀이 제작되었다. 그 결과 1.25V와 2V구간에서 10㎷ 미만의 오차 내에서 셀이 선형적으로 프로그램 되는 것을 보았다. 이러한 실험 결과를 이용하여 프로그램 가능한 A/D 변환기의 동작이 Hspice에서 시뮤레이션 되었으며, 그 결과 A/D 변환기가 37㎼의 전력을 소모하고 동작주파수는 333㎒ 정도인 것으로 관찰되었다.
